Benefits of technology

The invention is a method of sludge filtration using a system that minimizes the space required for the filter, can be attached to different container shapes and sizes, and can be easily removed and replaced. The filter is made of a mesh filter media resting against a support net, which is attached directly to the walls or floor of a container. The filter can be removably attached to the container using a two-part fastener system. The technical effects of this invention include efficient and effective sludge filtration in a compact space, and the ability to easily clean and replace the filter.

Problems solved by technology

For a large sludge container, such as a commonly practiced roll on roll off container, the weight of the plate and filters increases the difficulty of removal and replacement.

Embodiment Construction

[0028]Referring to FIGS. 1 and 2, a sludge filter 10 is depicted installed in a typical sludge container 30. Referring to FIGS. 1 and 2, a typical container 30 includes a container floor 32, opposed sidewalls 31, a rear wall 36, and a front wall 38. The container floor 32, sidewalls 32, rear wall 36 and front wall 38 are sometimes referred to herein as container 30 surfaces. The top 34 is typically open to receive sludge. A cover, not shown, may be provided.

[0029]Referring to FIG. 3, in a cross-sectional view of the sludge filter 10, the sludge filter 10 comprises a filter media 24 and a net 26. In an exemplary embodiment, filter media 24 comprises a planar mesh having multiple water-permeable openings extending transversely through the media 24. A preferred material of filter media 24 is a pliable polypropylene, nylon, polyester or wire mesh material. The openings in filter media 24 may be determined in relation to the maximum size of particulate matter that is acceptable to pass t...

Abstract

A method of filtering sludge solids from sludge liquids utilizing a sludge filter comprised of a rigid, yet deformable, filter media and a support net. The support net includes a front surface adjacent the filter media and a rear surface opposite the filter media, the rear surface having a plurality of outwardly extending nodes to define flow channels for horizontal and vertical fluid flow intermediate the net and a surface. A border of the sludge filter comprises one part of a two-part fastener system with a second part of the two-part fastener system attached to a surface along the perimeter of the filter coverage area, so that the filter medium may be removably attached to the surface.
